Request for subsystem 'sftp' failed on channel 0

[Norm Fredrick]

Hello,

I installed OpenSSH_3.7p1 on 2 AIX 4.3.3 servers last week and had this
problem on both of them. On the first server I finally re-installed the
package and that fixed it. I tried
re-installing it multiple times on the second server and still have the same
issue. I have checked everything that I can think of and spent many hours
looking for a solution. Both servers have the same csh.cshrc and csh.login
files. I don't have a personal .cshrc file on either server. I have many
more servers to install this on and would appreciate any help I can get to
solve this issue. Thank you.

Here is some of what I have and see:

OpenSSH_3.7p1, SSH protocols 1.5/2.0, OpenSSL 0.9.7b 10 Apr 2003
